IMPROVEMENT IN BEAMS: AND ROLLERS FOR LOOMS.

Specification forming part of Letters Patent No. 137,672, dated April 8,1873; application filed March 12, 1873.

To all whom it may concern:

Be it known that I, GEORGE LAWRENCE GARSED, of Wilmington, in the countyof New Castle and State of Delaware, have invented a new and usefulImprovement in the Construction of the Yarn-Beams, Cloth- Beams, andWhip-Rollers of Looms; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing forming part of this specification.

The object of the invention is to remedy the tendency in'the wooden yarnand cloth beams, and the whip-rollers of looms, to shrink and becomewarped at their junction with the heads or pulleys, and thus to allowthe heads to lean at an oblique angle thereto. This has the effect tocause the yarn to be wound unevenly on the yarn-beam, and to create,when unwound, an unevenness of tension, which produces a want ofuniformity in the cloth.

Heretofore these wooden beams have reccived the heads directly on theirends, and been secured by screws or bolts, which passed through anannular flange projecting from their sides; or they have been driven onand made fast by some equivalent means. The journals have been generallydriven into the ends of the beams or rollers. In passing throughcloth-mills many of these pulleys may be observed leaning obliquely tothe beams.

The ordinary mode of adjusting the heads when out of true position is todrive wedges between the head and the roll; but it only removesthedifficulty partially and temporarily. To remedy this defect Iconstruct the beams and whip-rolls in a single piece or in curvedsections. I construct the heads in a manner that will adapt them toreceive the ends of the roll or of the sections, and hold them fixedlyin position independently of the shaft.

In the drawing, Figure l is a view of the sectional beam or roll andindependent shaft attached to one of the heads. Fig. 2 is a view of therecess in the head which receives the ends of the sections. Fig. 3 is anelevation of the inside of pulley. Fig. 4 is a view of the sectionsglued together or otherwise connected so as to form a whip-roll.

A A are the heads, having recesses a a and fixed dogs 61 d,- B, the beamor roll, formed of sections 1); and O, the independent shaft, aboutwhich the sections are fastened. The heads A A are placed over each endof the shaft and drawn toward each other until they receive the ends ofsections 1) in their recesses a a, when they are clamped to shaft (3 bysetscrews 0 passing through the fixed collarsor hubs a M. D is a collarwhich surrounds shaft 0, and is, at or near the middle, rigidly attachedto it, having a projection, d, that rises between two sections of thebeam or roll, and serving the same purpose as the dogs 01 in the heads.

In case of the whip-roll, represented in Fig. 4, the heads or end caps Aare of the same size as the roller, but in other respects areconstructed like the heads, as shown in Figs. 1 and 2.

The sections 12 may be formed to rest longitudinally upon the shaft 0along its whole length without departing from the principle of myinvention, or they may be rigidly attached together, or the roll may bemade in one tubular piece, the mode of application to the heads beingessentially the same under all these modifications.

I do not confine my mode of putting together pulleys and shafts to theparticular uses mentioned, but intend that the protection craved shallembrace all analogous uses for which my invention is adapted.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

The shaft and its heads secured thereto, provided with recesses and withdogs to retain in position the beam or roll formed from one or morepieces, substantially as described.

GEORGE LAWRENCE GARSED.
